Abstract (en)
An air pollution control apparatus (10) according to an embodiment of the present invention has a denitration catalyst layer (13) that removes NOx in flue gas (12), and atomizes HCl into the flue gas (12) to oxidize Hg, and also includes a swirling-flow generating member (30A) that includes a swirling-flow generating-member body being partitioned to correspond to each passage of the denitration catalyst layer (13) and a plurality of swirling-flow generating vanes arranged on the partition inner walls to generate a turbulent flow, on an inlet (13a) side of the denitration catalyst layer (13). With this configuration, a laminar flow of the flue gas (12) in a flue gas duct (19) is changed to a swirling flow, thereby enabling to increase a contact time between the flue gas (12) and a denitration catalyst and to improve the oxidation reaction efficiency between Hg in the flue gas (12) and the denitration catalyst.
